🩺 MedCAT v2.7 Release Notes

This release focuses on usability improvements, pipeline observability, and several bug fixes across MedCAT components, including fixes for RelCAT and MetaCAT behaviour.

🚀 New Features & Enhancements

• Pipeline Timing / Speed Metrics – Added options to report the time spent in different pipeline stages, including:
  • Tokenisation
  • NER
  • Entity linking
  • Individual addon components
    This helps users understand performance bottlenecks in their MedCAT pipelines.
• Shorthand DeID Imports – Added a simplified import path for the DeID model:

  from medcat.deid import DeIdModel

  This replaces the longer internal import path previously required.

• Australian Model Bundle Support – Added explicit support for AU model bundles, enabling easier building and distribution of Australian clinical models.

🐛 Bug Fixes

• RelCAT Usability Fix – Fixed a typo that prevented RelCAT (relation extraction) from functioning correctly.
• MetaCAT Shuffle Fix – Corrected an issue where shuffling could still occur even when shuffle was disabled.
• RelCAT Typing Fix – Resolved typing issues affecting RelCAT components.
• Supervised Training Improvements – Improved the way supervised training synchronises entities in documents with expected dataset annotations.
  This simplifies batched training workflows for some linker implementations (e.g. embedding linker) and prevents edge cases where batched annotations could remain unprocessed.

🧰 Other Improvements

• Documentation Migration – MedCAT documentation has been migrated to MkDocs, improving maintainability and navigation.
• Tutorial & Script Automation – Fixed issues with the script used to automatically update tutorial and script versions.

This release improves pipeline transparency, training robustness, and component usability, while continuing to stabilise the MedCAT v2 ecosystem.
